Application led October 7, 1921.

This invention comprises a mechanism in which the outlet or outlets of a centrifugal rotor are coordinated with a receptacle or receptacles provided with heating means by which a viscous substance orsubstances separated in the operation can be raised in temperature and fluidity to facilitate yits discharge.

Petroleum containing petrola'tum or petroleum wax has been successfully treated for the separation of the wax, by chilling the wax bearing oil to precipitate the wax and separating the chilled constituent in a centrifugal rotor containing a carrier liquid, as brine, of greater density than the wax, the wax and the wax freed oil being separately discharged to different receptacles or covers The chilled wax, which is kept `from contact with the wall of the bowl by the brine, adheres to a greater or less degree to the receptacle or cover into which it is discharged, with a tendency to accumulate therein and limit the time during which the operation can be carried on continuously, by reason of the necessity for the removal of such wax.

' llnma-ccorda'nce with my invention, the separated viscous constituent (particularly the wax separated from petroleum) discharged from a centrifugal rotorI is heated and. rendered sutliciently Huid to flow by gravity from the cover into which it is ischarged.

lin the preferred practice of my invention as applied to the separation of waxp from wax caring petroleum, the compartment for receiving the `wax discharged from the centrifugal rotor is disposed between top and bottom compartments for .holding a yheating Huid, preferably hot water, and an insulating compartment is provided between Y the carrier liquid and the adjacent heating compartment.

The invention is .comprised in the construction set out in the following description, illustrated by the accompanying drawing. s The drawing is a broken sectional Aview showing` the top of a centrifuge having covers providlng com artmentsfor receiving the effluents toget er with compartments for holding a fluid for heating the wax compartment,"and a compartment for f partment, with het top and vbottom walls,

containing air as an insulating medium beydispose CENTRIFUGAL SEPARATOR.

tween the brine compartment and the adja cent hot water compartment. v i

In the drawing, the centrifugal rotor 1 is provided with the neck 2 by which it is suspended and revolved and with the passages 3, 4 and 5 through which the centrifugally separated and stratified constituents are discharged.-

In the separation of wax from chilled oil and the use of brine as acarrier liquid, the brine discharged from the rotor flows by Way of the passages 3 to the channel 6 and thence over vthe Weir or dam 7, concentric with the axis of'revolution; the wax separat-ed from the oil iows from the passages 4 through `the chamber 8, over the weir or `dam 9 concentric with the axis of revolution, and thence through the passage or passages 10; and the oil freed wax flows by way of the passages 5 to the channel 1l and thence over the weir or dam 12 concentric with the axis of revolution.-

A cover 13 is supported detachably by the case 14, contains the compartment 15 concentric with the bowl and disposed so as :cal/bottom, thereby heating the wax ei'luentin the compartment and facilitating its discharge therefrom through the spout 17.

.The cover 18 is supported detachably on the cover 13 concentric with the bowl and is (provided with the compartment 19 so as to receive the brine discharged over the wein 7. This cover has a bottom compartment 20, for holding hot Water to heat the' compartment 15 with the wax therein, and a compartment 21 between the compartments 19 and 20, for holding air to insulate the compartments 1.9 and 20z prevent t eunnecessary communication o heat to the compartment 19 and conserve suon heat for use inl the compartment 15.

A cover 22 is supported detachably by the cover 18, concentric with the rotor,

and'provides a compartment 23 in position for receiving the oil discharged over the Weir 12.

It will now be understood that in the operation. of the machine the chilled wax is delivered from the rotor into a heated comand is rendered sufficiently fluid by heat eX- change to discharge freely by gravity through the spout 17, the brine and wax freed oil flowing off from their Irespective compartments 19 and 23 through the respective spouts 24 and 25.

Having described my invention, I claim :e

\ l. A centrifugal machine lcomprising a rotor having means for separately discharg-q ing constituents of differentI densities `of a substance separated in said rotor, an efuent collector with which a constituent makes initial contact on its discharge from said rotor Aand over which it flows to a discharge point,

and means for maintaining a heating fluid in contact with the exterior of said collector over an area substantially equal to the area' of the path of flow of said effluent and heating the collector sectiony with which said constituent makes initial contact.

2. A centrifugal machine comprising a rotor having means for separately discharging constituents of different densities of a substance separated in said rotor, an elliuent collector with which a constituent makes initial contact on its discharge from said rotor, and over which it flows to a discharge point, and means for maintaining a heating fluid out of contact with the effluent and in contact with the collector over an area substantially equal to the area with which said effluent makes contact bet-Ween its discharge,

from said rotor and its discharge,` from said collector.

3. A centrifugal machine having, in combination with a rotor provided with outlets for separated constituents, covers provided with compartments for receiving the respective constituents and one -or more compartments for holding a heating fluid in contact with a wall ,or walls of a compartment vagainst which an out-let ldelivers a constituent. o

4. A centrifugal machine having, in combination with a rotor provided with outlets for separated constituents, of covers providing respective compartments in which said outlets discharge, a plurality of said covers having bottom compartments for containing a heating fluid for heating an intermediate compartment and the eflluent therein.

5. A centrifugal machine having, in combination witha rotor provided with outlets for separated constituents, of superposed covers having respective compartments regiaering .with Said waas, the bottom @over I- having a bottom compartment adapted for holding a heating fluid, and a second cover having a bottom compartment for holding a heating fluid and a compartment for holding an insulating fluid.

6. A centrifugal machine comprising a rotor provided with a discharge passage for an adhesive substance liquefiable by heat and a discharge passage for a liquid,a receptacle to which said rotor directly dischar es said substance,'means for heating said su stance, and means for impeding heat transfer be- -tween said heating means and said liquid.

port for a liquid separated therefrom, and a discharge port for a carrier liquid, a heater immediately adjacent to thel point of discharge of said substance from the rotor, and

separate receptacles for the reception of the said rotor, one of liquids discharged from interposed between said receptacles bein said heater and the -ot er of said` receptacles' and forming a heat insulator therefore.

10. A centrifugal machine comprising a rotor for separating andseparately discharging constituents of a substance, means for heating one of said constituents duringithe discharge thereof, and means for impeding heat transfer betweenl said heating means and the other of said constituents during the discharge thereof. t

In testimony whereof I have hereunto set my name this 4th day of October, 1921.
